摘要：随着我国汽车制造工艺逐步完善，汽车制造行业开始重点研发新能源汽车，电子诊断技术使维修工作逐步升级，进一步推动了新能源汽车行业的发展。但是，新能源汽车结构精密，传统汽车故障诊断技术适用性较差，存在检测手段单一、结果准确率低的技术缺陷。本文对电子诊断技术在新能源汽车维修领域中的应用现状开展探讨，对技术未来发展进行探索，希望可以全面提高新能源汽车的故障诊断质量和维修效率。

Abstract： With the gradual improvement of my country's automobile manufacturing process， the automobile manufacturing industry has begun to focus on the research and development of new energy vehicles. Electronic diagnostic technology has gradually upgraded the maintenance work and further promoted the development of the new energy vehicle industry. However， the structure of new energy vehicles is sophisticated， and the applicability of traditional vehicle fault diagnosis technology is poor. There are technical defects such as single detection methods and low accuracy of results. This article discusses the application status of electronic diagnosis technology in the field of new energy vehicle maintenance， and explores the future development of technology， hoping to comprehensively improve the quality of fault diagnosis and maintenance efficiency of new energy vehicles.

1  电子诊断技术概述

1.1 基本认识  电子诊断技术，采取全新的电子检测手段，在不拆除新能源汽车车身结构的前提下，通过所采集原始特征信号的分析结果，即可快速掌握汽车各部位实时运行状态，准确判断新能源汽车是否处于异常运行问题，锁定具体故障点位、明确故障类型与出现成因。而具体诊断步骤为，维修人员使用电子设备快速获取故障码，对故障码进行读取识别，从而判定新能源汽车故障类型，为后续汽车维护检修工作的开展提供信息支持。

1.2 应用意义  在传统汽车故障诊断模式中，受到技术限制，往往采取目视检查法与排除法，观察车身结构外观质量、各部位运行情况来锁定故障点，故障诊断工作效率较为低下，实际工作量较大。同时，故障诊断结果准确性还将受到人为主观因素的干扰影响，存在不确定性。……
